Part Number: SPM-1
Title: STEREO PERFORMANCE METER
Category: Test Equipment
Industry: TV/Radio Broadcast, CATV Cable Industry,
The SPM-1 STEREO PERFORMANCE METER measures the stereo content present in any left and right audio program material. This instrument is an entirely new concept in stereo measurement that actually computes the stereo separation of the Left and Right audio channels and displays the result on an LED bar-graph display in realtime calibrated in 1 dB steps from 0-50 dB. Polarity inversion is also displayed when the Left and Right audio channels are inverted.
Use the SPM-1 to measure and set the actual stereo separation present on any given mix-down. This unit does for stereo performance measurement what the VU meter does for audio volume measurement. You wouldn’t work audio without a VU meter, and you shouldn’t work stereo without a Stereo Performance Meter.
This unit measures the exact degree of stereo separation for each segment of the program, allowing precise control of stereo “focus”, audio image and expansion to any specific desired separation. The LED bar graph displays stereo separation in one dB steps over a range of 0-50 dB. Stereo inversion is also indicated on a static and dynamic basis.
Stereo separation measurement is independent of the audio volume level and the unit will measure true separation at any program level. Put this new technology to work for you. It will save mix-down time and improve stereo performance throughout your product.
